HEEL.

2 0 all whom it may concern:

Be it known that I, THOMAS J. ONnILL,

a citizen of the United States, residing at Tampa, in the county of Hillsborough and State of Florida, have invented certain new and useful Improvements in Heels; and I do hereby declare the following to be a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in shoe heels.

The object of this invention is to provide the shoe and heel with novel means whereby the heel may be removably fastened to the shoe and the heels of a pair of shoes interchanged so as to permit the heels to be worn evenly, thus prolonging the life of the heels.

A still further object of this invention is to provide the heels and shoes with means whereby the heels may be detachably secured to its respective shoe 'and changed when Figure 1 is a longitudinal sectional view illustrating the heel and shoe equipped with novel means whereb the heel may be de lachably secured to t .e shoe,

Fig. 2 is a transverse sectional viewof the heel applied to a shoe,

Fig. 3 is a similar view,

Fig. 4 is a perspective view of the heel with my improved attachment thereon.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

Referring to the drawing, the numeral 5 designates a fragmentar portion of a shoe equipped with a sole 6 w ich extends for the full length of the shoe from heel to toe thereof.

A metal plate 7 is secured by the fastening means 8 to the heel portion of the sole 6 as Specification of Letters Patent. Patented Sept. 16, 1919. Application filed December 14, 1917. Serial No. 207,111. I

illustrated in Fig.. 1 and this late has its peripheral edge bent downwardly and outwardly to provide a retaining flange 9, which retaining flange 9 extends around the periphery of the plate 7 and has its forward edge bent downwardly and upwardly to provide a clamping tongue 10, and the terminal of the clamping tongue .is bent forwardly to provide a manipulating finger 11.

The shoe heel is designated by the numeral 12 and has secured on its upper side a plate 13. .The peripheral edge of the plate is bent upwardly at right angles thereto to rovide a flange 14, the terminal of which ange is bent inwardly as at 16 to provide a supporting flange. which is adapted to engage the retaining flange 9 of the plate 7 to removably secure the heel in position upon the shoe.

The forward edge of the plate 13 is provided with a transversely extending slot 17 which slot has its inner wall located beyond the forward wall 18 of the heel 12. The

extreme forward edge of the plate is curved the weight of the heel now in general use.

In use, the plates 7 and 13 respectively are secured to the shoe 5 and heel 12 respectively in the manner described. The supporting flange 1601? the plate 13 carried by the heel is adapted to engage over the retaining fiange9 of the plate 7 carried by the shoe, thus the heel may be moved into and upon the shoe until the slot 17 registers with the tongue 10 and is automatically forced into the slot and retains theheel in position. It-

being apparent that it is only necessary to raise slig tly upon the manipulating finger 11 of the plate 7 releasing the tongue 10 from the slot 17 to permit the heel to be removed and interchanged so as to cause the heel to wear evenly on all sides.

Having thus described my invention, what I claim is:

A detachable heel comprising tion, a lower plate secured to the heel section, an upper plate adapted to be secured to a heel seca shoe, interlocking U-shaped flanges carried by the plate, and a tramsyersely. extending tongue carried by the forward edge of said upper plate, the forward portion of said lower plate being extended beyond said heel and having a recess for receiving-the transyersely extending'tongue of said upper plate,

the terminal portions of said tongue andtll'eneieeos lower plate being curved transversely and inter-leaked.-

In testimony whereei I afiix my signature in presence of two witnesses.
